Many times, different projects require different node versions. We constantly switch versions to develop projects. Uninstalling and installing again and again is very inefficient, so we can use nvm (node version manager) to manage the node version. Every time When using different versions, you can switch the node version through nvm
1. nvm installation
First we download nvm, download address: https://github.com/coreybutler/nvm/releases, we download the installation version of setup, as shown below
After the download is complete, unzip and install. The following figure shows the installation address.
Then the shortcut address, then keep clicking next until installation
2. Install node
After the installation is successful, you can install node through the nvm command, such as
nvm install 14.7.0 // 安装14.7.0版本的nodejs
When installing multiple node versions, you can use nvm use version number to switch versions.
nvm use 14.7.0
Check which node versions are available in local nvm
nvm list
3. Modify the image
The default npm address downloads resources very slowly, so we modify the mirror address to increase the resource download speed. Choose one of the following 设置npm镜像and the other two安装cnpm镜像
-
View mirror address
npm config get registry -
Set npm mirror (directly modify npm mirror address)
npm config set registry https://registry.npm.taobao.org -
Install cnpm image (modified npm default image, no need to install cnpm)
npm install -g cnpm --registry=https://registry.npm.taobao.orgJust replace it with cnpm when using the npm command in the future.
4. Install vue
After we install node, we can install vue to create a vue project
npm install -g @vue/cli
